In the title compound, C15H10F2O3S, the 3-fluorophenyl ring makes a dihedral angle of 79.51 (6)° with the mean plane [r.m.s. deviation = 0.006 (2) Å] of the benzofuran fragment. In the crystal, molecules are linked by weak C—H⋯F and C—H⋯O hydrogen bonds. The crystal structure also exhibits slipped π–π interactions between the benzene and furan rings of neighbouring molecules [centroid–centroid distances = 3.563 (3) and 3.820 (3) Å and slippages of 0.358 (3)and 1.551 (3) Å]. In the 3-fluorophenyl ring, the F atom is disordered over two positions with site-occupancy factors of 0.887 (3) and 0.113 (3).
